I just wanted to share my experience with this method. I've been doing this for 2 months now, and I'm finally starting to see encouraging results.
This is not as easy as it sound, since you have to find a good proxies provider, good IG accounts provider, a working method to phone verify those accounts, and most importantly, good niches.
Then you have to invest in those proxies, accounts, domain names, hosting, MassPlanner (or FollowLiker), and VPS.
I spent the first month facing a lot of bans, and I lost more money than I earned. Then things settled down for a few weeks. Now I still get the occasional ban waves. I lost 15 accounts yesterday, when nothing linked them together. Different proxies, different bios, different links, different prelanders, different phone numbers...
My earnings are for 35 accounts running for 2 different niches. I will increase that number to 50 accounts for those 2 niches, but I will have to find new niches after that.
In case you're wondering, I'm using custom landing pages.
